Birch by Helix Down Duvet Insert

The blend of 70% white down and 30% wool combines the plush, lofty insulation of down with the moisture-wicking and temperature-regulating properties of wool. This makes the duvet exceptionally breathable, helping you stay warm in the winter without overheating during warmer months.

Baffle box construction uses internal fabric walls to create individual pockets for the fill. This design prevents the down and wool from shifting or clumping, ensuring the loft remains even across the entire duvet so you don't end up with cold spots.

Yes, this insert is designed to be compatible with standard duvet covers. It features corner loops that allow you to tie it securely inside your cover, preventing the insert from sliding around or bunching up while you sleep.

Yes, the fill is Responsible Down Standard (RDS) certified. This certification ensures that the down and feathers come from ducks and geese that have been treated humanely throughout their lives.

Yes, it is designed as an all-season insert. The combination of breathable organic cotton and the natural temperature-regulating properties of the wool-down blend makes it versatile enough to keep you comfortable through changing seasons.
